What is epiphysis metaphysis and diaphysis?
FMA. 24012. Anatomical terminology. The epiphysis is the rounded end of a long bone, at its joint with adjacent bone(s). Between the epiphysis and diaphysis (the long midsection of the long bone) lies the metaphysis, including the epiphyseal plate (growth plate).
What are the 4 parts of the bone?
Anatomy
- Periosteum: The periosteum is a tough membrane that covers and protects the outside of the bone.
- Compact bone: Below the periosteum, compact bone is white, hard, and smooth. It provides structural support and protection.
- Spongy bone: The core, inner layer of the bone is softer than compact bone.
What are the 5 major parts of a bone?
List five major parts of a long bone. Epiphysis, diaphysis, periosteum, yellow marrow, medullary cavity, compact bone, spongy bone, articular cartilage.
What is the epiphysis of the bone?
epiphysis, expanded end of the long bones in animals, which ossifies separately from the bone shaft but becomes fixed to the shaft when full growth is attained. The epiphysis is made of spongy cancellous bone covered by a thin layer of compact bone.
What are the 3 major differences between the epiphysis and diaphysis of long bones?
| Epiphysis vs Diaphysis | |
|---|---|
| The epiphysis is the wider section at each end of the long bone which is filled with spongy bone. | Diaphysis is the shaft of a long bone, which runs between the epiphysis. |
| Texture | |
| The epiphysis is cartilaginous structures and less hard. | Diaphysis is a hard structure with compact bone. |
| Components |
What is the epiphysis function?
The epiphysis is the rounded end of a long bone. Epiphyses are rounded because long bones form joints with other bones; the rounded shape lets them move more smoothly in the joint, giving you more motion.
What’s the difference between the epiphysis and the diaphysis of the bone?
A long bone has two parts: the diaphysis and the epiphysis. The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled with spongy bone.
Which bone contains a diaphysis?
The diaphysis is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat)….

What is metaphysis in bone?
The metaphysis is the region where the epiphysis joins the diaphysis; in a growing bone this corresponds to the calcified layer of the epiphyseal plate together with the interdigitating bone (see Figure 4.19). When a long bone has achieved its mature length, longitudinal growth in the epiphyseal plates ceases.
